Description
Version:
- Particularly suitable for highly dynamic milling applications.
- Optimised outer contour due to FEM (finite element method) – robustness due to maximum rigidity, longer tool lives, higher metal removal rate, suitable for all machining strategies.
- With RFID/Balluffchip bore.
- Axial length adjustment, adjustment travel 10mm.
- Reducing adapters can be used.
- Temperature resistant up to 170°C for 4 hours.
- Up to 10× more clamping operations possible compared to a standard hydraulic chuck.
- Very low tightening torque of the clamping screw – easy handling.
- Patented new hydraulic clamping system – reliable, durable premium radial run-out.
Application:
Universally designed for roughing and finishing operations. For clamping tools with shank tolerance h6.
Optional extras:
Coolant tube No. 309880. socket wrench No. 309890, reducing adapters No. 302140; 302135 302145 302147 each size 12 and No. 302150; 302155; 302160; 302165 each size 20.
Warning:
Intended use
Reasonably foreseeable misuse
- Hydraulic chuck for clamping rotationally symmetrical tools.
- For work in industrial environments.
- Observe minimum clamping depth.
- If using custom designs, observe the specifications in the applicable drawings.
- Observe the maximum operating speed and adapt it to individual conditions if necessary.
Reasonably foreseeable misuse
- Do not use in explosion hazard areas.
- Not for use in areas where high concentrations of dust, flammable gases, vapours or solvents are present.
- Do not combine extensions.
- Not to be used for workpiece clamping.
- Do not heat with a shrink-fit unit.
